Mark Scheme
INPUT Distance
INPUT Passengers
Extra = Distance - 1
CostofExtra = Extra * 2
Cost = 3 + CostofExtra
IF Passengers > 4 THEN
Surcharge = Cost / 2
Cost = Cost + Surcharge
END IF
OUTPUT Cost
Award marks for:
Inputs distance and passengers
Calculates distance -1 (or equivalent)
Calculates previous answer * 2 (or equivalent)
Calculates previous answer + 3
Checks if more than 4 passengers...
...and adds 50% correctly
Outputs cost
